| ninhydrin reaction | <technique> A technique for detecting amino acids and proteins by heating a material with ninhydrin, if amino molecules are present, there is a colour reaction. (09 Oct 1997) |
| ninhydrin-Schiff stain | <technique> For proteins, proteins are revealed by using ninhydrin or alloxan to produce aldehydes from primary aliphatic amines by oxidative deamination; the aldehydes are shown by reaction with Schiff's reagent. (05 Mar 2000) |
